本文通过结构变形对天线电气性能影响的分析,拓广了保型设计和最佳匹配设计思想,提出和构思了凸变形面天线结构的构造方案,配合运用考虑绕射效应的指向角上副面形状予优设计方法,实现了双反射器天线的高效率设计。这一方法计算精确,效果明显,所构造的结构简单易行,对中小口径天线尤为适用。通过对五米天线的探讨,证明具有实用意义。 Based on the analysis of the effect of structural deformation on the electrical performance of the antenna, this paper extends the concept of conservative design and best matching design, proposes and constructs the structural scheme of the convex deformed antenna structure, Shape to the preferential design method, realized the high efficiency design of the dual reflector antenna. This method is accurate, the effect is obvious, the structure is simple and easy to construct, particularly suitable for small and medium diameter antenna. Through the discussion of five meters antenna, proved to be of practical significance.
